DAC yokhala ndi amplifier yam'mutu iFi NEO iDSD
iFi NEO iDSD ndi chophatikizira chomvera, m'lingaliro lonse la mawuwa. Zida zomvera zimaphatikiza DAC, preamplifier ndi amplifier yokhazikika yam'mutu, ndi kuthekera kotumiza ma data opanda zingwe. Ichi ndi chipangizo chokhala ndi kudzazidwa kozizira kwambiri kwamagetsi, komwe kulibe zinthu zamtundu uliwonse kuti ziwongolere phokoso ndi zosefera. Akatswiri a kampaniyo sanasunge chilichonse pano. Zotsatira zake ndikuchita bwino kunja kwa bokosi.
iFi NEO iDSD DAC ndi Amplifier - mwachidule, mawonekedwe
Chipangizocho chili ndi microcontroller ya 16-core XMOS yomwe imavomereza deta kuchokera ku USB ndi S/PDIF zolowetsa. Mosiyana ndi zida zam'mbuyomu za kampaniyo, imagwiritsa ntchito chip chokhala ndi liwiro la wotchi kawiri komanso kukumbukira kanayi. Kuti athetse jitter, GMT femto-clock imayikidwa, yomwe imagwira ntchito limodzi ndi kukumbukira kukumbukira. Chip cha DSD1793 chochokera ku Burr-Brown ndi chomwe chimapangitsa phokosolo.
NEO iDSD idakhazikitsidwa pagawo lofananira la "PureWave" lomwe limagwira ntchito pawiri mono yokhala ndi njira zazifupi zolumikizirana kuti mukwaniritse mzere wapadera komanso chiyero cha sonic ndikuchotsanso crosstalk. Amplifier yayikulu yogwiritsira ntchito ndi OV2637A yachizolowezi. Kuwongolera kwa voliyumu kumayendetsedwa ndi dera lozungulira la analogi. Zomwe zimayendetsedwa ndi microprocessor control, kuti mupeze zolondola kwambiri.
Kutulutsa kwamutu kumayendetsedwa pogwiritsa ntchito transistor ya OV4627A J-Fet ndi W990VSI attenuator. Kuti kuwonjezera pa khalidwe lapamwamba amapereka mlingo wotsika wa phokoso ndi kupotoza. Inde, izi zimachitika pazida zomvetsera zapamwamba, ndipo iFi NEO iDSD ikuwonekeratu mwapamwamba. Gawo la amplifier yam'mutu limatha kupereka mphamvu yopitilira 1000mW mu 32 ohms.
Chipset chapamwamba cha Qualcomm QCC5100 Bluetooth chimathandizira ma codec onse amakono. Kuphatikiza apo, imatumiza mawu apamwamba kwambiri, mpaka 24bit / 96kHz. Kuti muchepetse kuwongolera, chipangizochi chimakhala ndi chowongolera chakutali komanso chiwonetsero cha OLED chomwe chili kutsogolo. Mwa njira, chipangizocho chikhoza kukhazikitsidwa molunjika kapena molunjika. Chifukwa chake, chiwonetserochi chimangotembenukira kumayendedwe osankhidwa. Kukonzekera ndikwabwino kwambiri.

Mndandanda wa NEO ndi yankho lapakatikati kuchokera kwa wopanga waku Britain iFi, pakati pa akatswiri a PRO ndi zida za ZEN za bajeti. Pogwira ntchito ya NEO iDSD, zinali zotheka kupereka okonda nyimbo ndi dongosolo lokhala ndi khalidwe labwino komanso mtengo. Pomwe gawo la ogwiritsa ntchito likhalabe odzipereka kuzinthu za iFi, ndipo gawo lina lidzamvetsetsa kuti ungwiro umayamba pati.
